IMPROVEMENT IN STOVES.

Specification l'orniingpart olf Letters Patent No. 24,791, dated July 6. i859.

To @ZZ whom t may concern: i

Be it known that I, PETER N. BURKE, of utfalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in CookingStoves; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, of which- Figure l represents a vertical longitudinal section through a stove. Fig. 2 is a perspective View showing one-half of the same and the direction of the currents by red and black arrows.. Fig. 3 exhibits the front of the stove, showing` the registers through which air passes into the lues. Fig. e represents the lower plate for forming the fluechamber underneath the heartheplate and fire-hearth.

The following description will illustrate the application of my principle to the common form of wood cook-store. The same principle may be also applied to various forms and descriptions of stoves, ranges, and ovens with only a slight alteration of the form and dimensions of the plates equivalently, thesanie principle being preserved throughout.

By reference to thc drawings the fire-hearth is represented by A, which is a corrugated plate. Below this hearth is arranged a plate 3, which, in connection with hearth A, forms an intermediate space O. The lower plate l5, which abuts against the front plates I) of the stove, has arranged upon its surface partitions E, which, when the two plates A l5 are brought together, formcompartments or tinespaces F, which direct the current of air as it is drawn in through the register-openings G to the rear part oi' the plate and return it to the central passage F', from whence it passes into the flue Il, the outer plate of which is corrugated, as in the hearth-plate. This fluespace directs the air upward, as indicated by the red arrows, and submits it to the heatingsurface of the lire-guard I, where it is dispensed over the perforated plate and equally diffused throughout the oven or ovens, as the case may be, as hereinafter described.

The products ot' combustion are carried over the corrugated plate J and to the rear part of the stove, where they are brought in con tact with the heated air rising from the oven through the hot-air pipe L, as indicated by the red and black arrows, these showing the di rection of the two currents through the stove. These currents, both tending to the common smoke-pipe, (not shown by the drawings,) meetin the chamber K, where the smoke, &c., is exposed to the highly-heated air, and thus consumed and passed off through a direct smoke-pipe5or it may then be employed to heat water which is contained in a boiler (not shown) partially surrounded with a jacket or casing, through which the heated air passes in communicating with the smokepipe connected with the top of this boiler. The air, having been subjected to the heatingsurfaces of plates A, I, and J, passes down through the perforations in horizontal plate Naud into the oven l of the stove and over and around the articles to be cooked, and thence through apertures in the oven-plate R and to the rear of the stove, where the air passes up through the pipe L into chamber K, as above specified. The arrangement and construction 'of these plates are very peculiar, iii-order to efect the desired purpose-viz., the equitable diffusion ot' the hot air throughout the entire oven from the time it commences to descend or pass through the perforations ot' plate N. I therefore arrange the perforations in the upper plate so as to conipensate for the different degrees of draft over its surface by making the perforations smallest where the draft is greatest and enlarging thein where there is the least draft. In this manner the hot air passes over the plate N to its rear end and is equally distributed in its descent and diffused throughout the entire oren. The lower plate Ris also perforated, but the order of perforations is reversed, the largest holes being placed where the draft would be the least and the smaller holes at the rear of the oven immediately below the larger perforations of the upper plate N. In this manner the temperature of air passing through the stove is not only increased, but the air is more economicallydistributed or diffused throughout the oven.

The regulation of the passage of air through the stove is effected by common registers placed below and on each side of the hearth, and when it is desired to radiate the heated air into the room the damper S in the hot-air pipe I. is closed, when the air passes out through apertures in said pipe arranged bef. 10W the damper, as indicated by red arrows The arrangement and combination of the of Fig. 1 in the drawings. perforated platesN R, the partitional plate B, I do not claim, broadly, the introduction of the flue H, the tire-guard 1, hot-air pipe L, hot air into the oven, nor do I claim anypart and chamber K, as and for the purpose or kfeature seen in the patents granted to herein shown and described.
